US 2026/0010218 A1 · ELECTRONIC DEVICE AND OPERATION METHOD THEREOF

Abstract

An operation method of an electronic device is provided. A busy-waiting instruction indicating that the operating system of the processing device is in a busy-waiting state is received. The processing device is in a virtual machine mode. A microcode of the busy-waiting instruction is obtained according to the registered value of the first register. The waiting enabling instruction is generated, and the first counting value corresponding to the waiting enabling instruction and the second counting value corresponding to the first system time are obtained according to the microcode. The first and second counting values are added to generate a third counting value and store it in a second register. According to the waiting enabling instruction, a subsequent microcode is stopped sending to the processing device, so that the processing device enters an idle state, and the counter is enabled to start counting according to the third counting value.

Dependent claims

An operation method of an electronic device, comprising:

receiving a busy-waiting instruction, wherein the busy-waiting instruction indicates that an operating system of a processing device is in a busy-waiting state, and the processing device is in a virtual machine mode;
obtaining a microcode of the busy-waiting instruction according to a registered value of a first register of the processing device;
generating a waiting enabling instruction, and obtaining a first counting value corresponding to the waiting enabling instruction and a second counting value corresponding to a first system time according to the microcode;
adding the first counting value and the second counting value to generate a third counting value and storing the third counting value in a second register of the processing device;
according to the waiting enabling instruction, stopping sending a subsequent microcode to the processing device, so that the processing device enters an idle state, and the counter is enabled to start counting according to the third counting value.

2 more elements
